Should you choose to use All Our Ideas again, there are community requests about some of the functionality which needs to be discussed with the team. I can put you in touch but will pass the contact info to @Johan . Main requests:

• Increase the # of characters in both question (current max 100) and suggestion (current max 150) - needs about 350 for the question; 500 max for the suggestion.
• Allow for hyperlinking

**There were also general concerns about pairwise ranking, though research by the Princeton sociologists who developed the tool...well, I trust their judgment on gathering this information. Also, even with the privacy settings, the internal analytics team was able to detect that some people were trying to game the system. It did not let them. So as far as getting a good ranking and possible gaming mitigation, I think it works well. The issue is that it doesn't quite feel that way to users who are used to a different model.
